Sinewave Dynamo Lights & Chargers
Sinewave Cycles is a small US company making premium dynamo-powered devices for cyclists. Their Revolution USB charger and Reactor dynamo headlight are widely regarded as the best available for touring and bikepacking cyclists who want reliable power generation from their wheel hub dynamo. For long-distance and self-supported NZ riders, Sinewave products are a serious upgrade.
Why Choose Sinewave?
Sinewave products are built to a standard that goes beyond what most cyclists expect from a dynamo accessory. Their engineering attention - from voltage regulation to heat management to mounting design - produces devices that work reliably across thousands of kilometres of varied conditions. For NZ tourers and bikepackers who rely on their devices, Sinewave delivers confidence.
Revolution USB Charger
The Sinewave Revolution is widely considered the best dynamo USB charger available. Its voltage regulation provides smooth, consistent charging output across a wide speed range - unlike many dynamo chargers that only charge effectively above a certain speed. Compatible with most modern devices and designed to work reliably at touring speeds on NZ's varied terrain.
Reactor Dynamo Headlight
The Sinewave Reactor is a dynamo headlight with a wide, even beam pattern optimised for touring use. Standalone or combined with a USB charging function, the Reactor provides reliable, powerful lighting from your wheel hub dynamo - no batteries to replace, no charging to remember on long NZ tours.
Beacon - Combined Charger and Light
Sinewave's Beacon combines USB charging and headlight output in a single unit, eliminating the need for separate charger and light components. The power management system prioritises charging or light as needed, providing a seamless dynamo system for NZ bikepacking and touring riders who want simplicity without compromise.
Dynamo Hub Compatibility
Sinewave products are compatible with the leading dynamo hubs including SON, Shimano and Shutter Precision. Their devices handle the varying AC output of different dynamo hubs and convert it reliably to stable DC power for USB charging and LED lighting.
For NZ Touring and Bikepacking
NZ's long-distance cycling routes - the Tour Aotearoa, Timber Trail, Alps 2 Ocean and countless others - demand reliable power management for navigation devices, lights and communication. A Sinewave system powered by a quality dynamo hub provides that reliability without dependence on batteries or charging stops.
